Experimental brain-controlled hearing aid decodes, identifies who you want to hear

Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing aids struggle to do. But now Columbia engineers are announcing an experimental technology that mimics the brain's natural aptitude for detecting and amplifying any one voice from many. Powered by artificial intelligence, this brain-controlled hearing aid acts as an automatic filter, monitoring wearers' brain waves and boosting the voice they want to focus on.

AI model uses serial imaging to predict lung cancer therapy response

(HealthDay)—For patients with locally advanced non-small cell lung cancer (NSCLC), deep-learning networks integrating computed tomography (CT) scans at multiple time points can improve clinical outcome predictions, according to a study published online April 22 in Clinical Cancer Research.

When science and politics collide: Support for enhancing FDA independence

Earlier this year, twin papers authored by seven former Food and Drug Administration commissioners, published by Health Affairs and the Aspen Institute on the same day, suggested that the FDA should become an independent agency.

Here's why your internet may be delivered by a drone someday soon

As the pilotless flying wing came in for a landing, winds suddenly picked up. Facebook Inc.'s Aquila drone—powered by the sun and wider than a Boeing 737 jetliner—struggled to adjust. Just before landing, part of the right wing broke off.

Electric car switch on for health benefits

Could the health benefits and reduced costs to healthcare systems be enough to justify subsidizing charging infrastructure to allow society to switch from the internal combustion engine to electric vehicles faster than current trends predict?

New AI sees like a human, filling in the blanks

Computer scientists at The University of Texas at Austin have taught an artificial intelligence agent how to do something that usually only humans can do—take a few quick glimpses around and infer its whole environment, a skill necessary for the development of effective search-and-rescue robots that one day can improve the effectiveness of dangerous missions. The team, led by professor Kristen Grauman, Ph.D. candidate Santhosh Ramakrishnan and former Ph.D. candidate Dinesh Jayaraman (now at the University of California, Berkeley) published their results today in the journal Science Robotics.

Long-term decline in stroke greater in older adults

Although the occurrence of first-ever ischemic stroke (strokes due to a blood clot that blocks a blood vessel in the brain) at middle age has been decreasing over time, researchers have found that the decline is not as steep as seen in older adults.

Bullet train champion in Japan will debut in 2030, now being tested

Testing for a train capable of 249mph (400 kph) speeds is to happen about twice a week at night. Bloomberg said ALFA-X is the world's fastest bullet train— well, for now, it is holding that title. Japan has also been working on a maglev train.

24 percent of West Antarctic ice is now unstable: study

By combining 25 years of European Space Agency satellite altimeter measurements and a model of the regional climate, the UK Centre for Polar Observation and Modelling (CPOM) have tracked changes in snow and ice cover across the continent.

Human antibody reveals hidden vulnerability in influenza virus

The ever-changing "head" of an influenza virus protein has an unexpected Achilles heel, report scientists funded by the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health. The team discovered and characterized the structure of a naturally occurring human antibody that recognizes and disrupts a portion of the hemagglutinin (HA) protein that the virus uses to enter and infect cells. The investigators determined that the antibody, FluA-20, binds tightly to an area on the globular head of the HA protein that is only very briefly accessible to antibody attack. The site was not expected to be vulnerable to such a strike.

Helping robots remember: Hyperdimensional computing theory could change the way AI works

The Houston Astros' José Altuve steps up to the plate on a 3-2 count, studies the pitcher and the situation, gets the go-ahead from third base, tracks the ball's release, swings ... and gets a single up the middle. Just another trip to the plate for the three-time American League batting champion.

Genomic collision may explain why many kidney transplants fail

A genomic collision could explain why many kidney transplants fail, even when donors and recipients are thought to be well-matched, according to a new study from researchers at Columbia University Vagelos College of Physicians and Surgeons. This genomic collision is a genetic incompatibility between kidney donor and recipient, causing the recipient to mount an immune attack against the donor protein.

I loved her, I loved her not: How current thinking can sway our memories of love

As our memories fade, we rely on our current assessment of a person to remember how we felt about them in the past, and new research suggests this extends to some of the most central figures in our lives: our parents. The findings are published in Clinical Psychological Science, a journal of the Association for Psychological Science.

What's causing your vertigo? Goggles may help with diagnosis

Vertigo is a form of severe dizziness that can result in a loss of balance, a feeling of falling, trouble walking or standing, or nausea. There is more than one type of vertigo, each with a different cause, and sometimes requiring different treatment. Now a proof-of-concept study has found that special goggles that measure eye movements during an episode of vertigo may help more accurately diagnose which type of vertigo a person has. The study is published in the May 15, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.
